In this embodiment, a capturing method is provided, fig. 2 is a flowchart of the capturing method according to an embodiment of the present application, and as shown in fig. 2, the flowchart includes the following steps:
step S202, acquiring a target image acquired by camera equipment;
step S204 of adjusting the image pickup apparatus to a target magnification based on position information of a target object in a case where the target object is included in the target image;
step S206, determining a target rotation angle range of the image capturing apparatus at the target magnification, wherein the image captured by the image capturing apparatus when rotating within the target rotation angle range does not include a dark angle;
step S208 of determining a target rotation angle of the image capturing apparatus based on the target rotation angle range, and controlling the image capturing apparatus to perform a snap shot operation after rotating the target rotation angle.
In the above embodiment, the image capturing apparatus may be a dome camera, and the image capturing apparatus includes a pan-tilt and a camera. The image capturing apparatus may analyze an image captured by the camera to determine whether an object of interest, i.e., a target object, exists in a region monitored by the image capturing apparatus. Wherein the target object may be a person, an article, a vehicle, etc. When the target object appears in the target image, the image capturing apparatus may be adjusted to the target magnification according to the position information in the image in which the target object is located, so that the target object may appear in the image in a predetermined ratio, where the predetermined ratio may be a ratio set in advance, for example, such that the target object occupies 75% of the entire screen (this value is merely an exemplary illustration, and may be 50%,60%,80%, or the like, which is not limited by the present application). And determining a target rotation angle range of the image pickup device under the target multiplying power, wherein no dark angle exists in the image acquired by the image pickup device when the image pickup device rotates any angle in the target rotation range.
In the above embodiment, the range of no dark angle that can be monitored by the lens frame is determined by the lens field angle and the range of no dark angle shielding of the lens housing, the range of no dark angle shielding of the device housing is determined by the hardware structure, and the same appearance product is consistent. The angle of view of the lens is inversely related to the focal length of the lens, and the focal length of the lens affects the imaging magnification, so that the angle of view of the lens is different at different magnifications. Therefore, the spherical camera equipment adopting the same lens shell can actually realize different rotation ranges without dark angles under different multiplying powers of the lenses.
In the above-described embodiment, after the target rotation angle range is determined, the target rotation angle of the image pickup apparatus may be determined from the target rotation angle range. After the image pickup apparatus rotates the target rotation angle, the target object is in the target field of view of the image pickup apparatus. Wherein the target field of view region may include a middle of field of view of the image capturing apparatus. When the target object is in the target field of view region, the snapshot operation is performed, and therefore, the efficiency of the snapshot can be improved.
Alternatively, the main body of execution of the above steps may be an image capturing device, or other devices with similar processing capability, or may be a machine integrated with at least an image capturing device and a data processing device, where the image capturing device may include a graphics capturing module such as a camera, and the data processing device may include a terminal such as a computer, a mobile phone, and the like, but is not limited thereto.
According to the application, the target image acquired by the image pickup device is acquired, the image pickup device is adjusted to the target multiplying power based on the position information of the target object under the condition that the target image comprises the target object, the target rotation range of the image pickup device under the target multiplying power is determined, the target rotation angle of the image pickup device is determined according to the target rotation range, and the image pickup device is controlled to execute the snap shooting operation after rotating the target rotation angle. Since the target rotation range of the image capturing apparatus is determined by the target magnification, that is, the target rotation ranges corresponding to different magnifications, and the image captured by the image capturing apparatus does not include a dark angle when the image capturing apparatus rotates within the target rotation range, the image captured by the image capturing apparatus is controlled to have no dark angle after the image capturing apparatus rotates by the target rotation angle determined by the target rotation range, and therefore, the problem of small capture view range caused by the fact that no dark angle exists in the captured image in the related art can be solved, and the effect of expanding the capture view range under the condition that no dark angle exists in the captured image of the image capturing apparatus can be achieved.
In one exemplary embodiment, determining the target rotation angle range of the image capturing apparatus at the target magnification includes: acquiring a first rotation angle range of the image pickup apparatus at a minimum magnification supported by the image pickup apparatus, and a first field angle; determining a second field angle of the image capturing apparatus at the target magnification; the target rotation angle range is determined based on the first rotation angle range, the first field of view, and the second field of view. In the present embodiment, the target rotation angle may include a horizontal rotation angle and a vertical rotation angle. In determining the target rotation angle, it may be determined by a first rotation angle range at a minimum magnification supported by the image capturing apparatus, a first angle of view of the image capturing apparatus at the minimum magnification, and a second angle of view of the image capturing apparatus at the target magnification.
In the above embodiment, the dynamic limit is performed on the pan-tilt according to the size of the angle of view under the minimum magnification of the lens and the angle of view in the zooming process, so as to provide the device with the largest possible field of view without any dark angle
In one exemplary embodiment, determining the target rotation angle range based on the first rotation angle range, the first field of view, and the second field of view includes: determining a difference between the second field of view and the first field of view; determining a first sum of the difference and a first minimum value in the first rotation angle range and a second sum of the difference and a first maximum value in the first rotation angle range to obtain a second rotation angle range; the second rotation angle range is determined as the target rotation range. In this embodiment, a dynamic limit diagram of the image capturing apparatus at a small magnification may be seen in fig. 3, and as shown in fig. 3, at a small magnification, the focal length of the lens is small and the angle of view is large. The range of angles in which the cradle head can rotate in the vertical direction is [ -A, +A ]. The dynamic limit diagram of the image capturing apparatus at a large magnification can be seen from fig. 4, and as the magnification increases, the focal length of the lens increases and the angle of view decreases as shown in fig. 4. In the vertical direction of the cradle head, the rotatable angle range is [ -B, +B ], and the horizontal direction is the same. The multiplying power is increased, and the rotation range of the cradle head without the hidden angle is also increased.
In the above embodiment, the image capturing apparatus may record the angle of view data (vertical angle of view ft1, corresponding to the above-described first angle of view) at the minimum magnification and the rotation angle range t1 (corresponding to the above-described first rotation angle range) without the dark angle, and acquire the angle of view data (vertical angle of view ft2, corresponding to the above-described second angle of view) at the current magnification in real time during the apparatus magnification change. The rotation angle range t2 (corresponding to the target rotation angle range) under the condition of no current dark angle is obtained through calculation. Wherein t2=t1+ (ft 2-ft 1).
In the above embodiment, starting from the basic principle that the dark angle appears on the lens picture, according to the negative correlation between the field angle of view of the lens and the focal length (picture multiplying power) of the lens, on the basis of obtaining the field angle data under the minimum multiplying power of the lens and the maximum rotation angle data of the holder under the minimum multiplying power, the maximum rotation angles of the holder under different positioning snapshot multiplying powers are dynamically calculated, so as to realize dynamic limiting.
In one exemplary embodiment, determining the target rotation angle of the image capturing apparatus based on the target rotation angle range includes: determining a rotation angle to be rotated when the image pickup apparatus rotates to a target field of view region of the image pickup apparatus; determining a target relation between the angle to be rotated and the target rotation angle range; and determining the target rotation angle based on the target relation. In this embodiment, after the target rotation angle range is determined, the rotation angle to be rotated when the image capturing apparatus rotates to the target field of view region of the image capturing apparatus may be determined, the target relationship between the rotation angle to be rotated and the target rotation angle range may be determined, and the target rotation angle may be determined according to the target relationship. And the transmitted rotation angle data can be judged according to the calculated real-time rotation range data without the hidden angle when transmitting the rotation angle instruction to the cradle head, so that the generation of the hidden angle of the lens picture is avoided on the software level, and the dynamic limiting positioning snapshot is realized. The target field of view region may be a field of view middle region of the image capturing apparatus, or any region in the field of view of the image capturing apparatus in which the image capturing apparatus can capture a complete target object.
In one exemplary embodiment, determining the target rotation angle based on the target relationship includes: determining the angle to be rotated as the target rotation angle when the target relationship indicates that the angle to be rotated is within the target rotation angle range; and determining the target rotation angle based on the to-be-rotated angle and the target rotation angle range including a second minimum value and a second maximum value in the target rotation angle range, in the case that the target relationship indicates that the to-be-rotated angle is outside the target rotation angle range. In the present embodiment, in the case where the angle to be rotated is in the target rotation angle range, the angle to be rotated is determined as the target rotation angle. When the angle to be rotated is out of the target rotation angle range, the target rotation angle is determined according to the maximum value and the minimum value in the angle to be rotated and the target rotation angle range.
In one exemplary embodiment, determining the target rotation angle based on the angle to be rotated and the target rotation angle range including a second minimum value and a second maximum value includes: determining the second minimum value as the target rotation angle under the condition that the angle to be rotated is smaller than the second minimum value; and determining the second maximum value as the target rotation angle in the case that the angle to be rotated is larger than the second maximum value. In the present embodiment, when the angle to be rotated is smaller than the minimum value in the target rotation angle range, the minimum value of the target rotation angle range is determined as the target rotation angle. When the angle to be rotated is larger than the maximum value of the target rotation angle range, the maximum value of the target rotation angle range is determined as the target rotation angle.
In the above embodiment, the maximum rotation angle of the pan-tilt under the current magnification can be calculated according to the positioning snapshot magnification, the positioning instruction issued to the pan-tilt is judged, and the limiting of the pan-tilt is controlled from the software level, so as to avoid the loss of the physical structure caused by adopting the physical limiting structure

fig. 5 is a flowchart of a snapshot method according to an embodiment of the present application, as shown in fig. 5, where the method includes:
step S502, obtaining a lens field angle and a cradle head rotation range under the minimum multiplying power;
step S504, receiving a positioning snapshot instruction;
step S506, calculating a rotation range of the cradle head under the snapshot multiplying power;
and step S508, positioning snapshot without dark corners.
In the foregoing embodiment, according to the characteristic that the field angle of view of the lens increases with the increase of the focal length, the magnification of the image decreases with the decrease of the focal length, and the pan-tilt rotation range without the dark angle is calculated in real time by calculating the value of the snap-shot magnification in the positioning snap-shot command, and the issued pan-tilt rotation command is judged according to the calculated range, so as to realize automatic dynamic limiting. According to the method, the maximum rotation angle of the cradle head capable of realizing no dark angle of a picture under the current multiplying power can be calculated according to the multiplying power when equipment is used for positioning and snapshot, and positioning and snapshot of the maximum monitoring visual field range can be realized by adjusting a positioning instruction according to the angle; according to the field angle of view of the lens at the minimum magnification and the maximum rotation angle of the holder at the minimum magnification, calculating the maximum rotation angles of the holders at different positioning magnifications on a software level, and carrying out limit control on the issued positioning rotation instruction, so that the stability is high, and physical damage of a holder hardware structure is avoided; dynamic cradle head limiting on a software layer, starting from the root cause of the generation of the hidden angle, according to the correlation between parameters such as the angle of view and the focal length of the lens, automatic limiting of the cradle head is realized, and meanwhile, the limiting high precision is ensured.
